To a'll whom it may concern:

opening 11 of the base,

Be it known that 1, Jumps Sonrm'rz, a citizen of the United States,residing at Shively, in the'county 'of Jefferson and State of Kentucky,have invented new and useful Improvements in Vises, of which thefollowing is a specification.

An object of the invention is to provide a vise for clamping bodies in arigid and stationary position.

The invention embodies, among other features, a device for clamping abody rigidly thereto, portions of the device being movable at variousangles to the vertical sothat a face of the body clamped in the vise canbe arranged at any convenientangle so'that the body can be easilyoperated upon.

The invention further embodies a vise having a stationary jaw and amovable jaw with means for quickly and efficiently operating the movablejaw to securely clamp a ence denote corresponding parts in all theviews, and in which:

I Figure 1 is a side elevation showing, the jaws in spaced relation,open position; Fig. 2 is a plan view; Fig. 3 is a vertical longitudinalsectional view taken on the line 3- 3 in Fig. 2, the vise being a bodyclamped bein closed position with. tween the jaws thereof; Fig. 4: is avertical transverse sectional view taken on the line 4-4 in Fig. 2; Fig.5 is a fragmentary perspective view of the cam head; and Fig.6 is aperspective view of one of the locking dogs.

Referring more particularly to the views, I employ a base 10 providedwith a semisphericalopening 11 in whichis movably mounted a ball member12 terminating in a threaded shank 13 extending upwardly from the ballmember. 12, a cap 1 1 being mounted on the base 10 and having threadedconnection therewith, an opening 15 being provided in the cap 1 1, thewalls of the said opening being inclined so that the said cap can beplaced over the ball 12 and then moved into threaded engagement with thebase 10 to retain the 'ballimember, 12 in the it being readily seen thatwhen the cap is screwed down on the 1 Specification of Iletters reten't.ap lication filed may as, 191a. serial no. 700,232.

disclosure of the invention the vise being in with the base 10.

ting shaft 28, a cam lever Patented Jan. 13, 1914.

base the ball member 12 will be held in stationary position relativelyto the base for a purpose that will be hereinafter more fully disclosed,a series of recesses 16 being preferably provided in the cap 14 for thereception of a spanner wrench or the like, whereby the cap can beconveniently rotated on the base 10 for the purpose of securing the capon or ofl' of the base. The threaded portion of the shank 13 hasthreaded connection with a bed plate 17 provided on the upper sidethereof with a depression 18, forming a seat, in which is mounted aplate 19 having the sides thereof extending beyond the sides of theplate 17 to form a track 20, the plate 19 being preferably secured tothe bed plate 17 by suitable screws passed through the plate 19 so thatthe upper faces of thescrews will fitfiush with the plate, the upper endof the threaded shank 13 being adapted to pass through an opening in theplate 19 and fit flush with the upper surface of the plate. An opening21 is formed in one end of the bed plate 17 and a dowel pin 22 isadapted to extend therethrough to extend into anopening 23 formed in thebase 10, thus retaining the bed plate 19 rigid relatively to the base10, the upper end of the dowel pin 22 being formed into a suitable knobor handle 24:, whereby the dowel pin can be easily removed fromengagement A vertically extending clamping jaw 25 is formed with the bedplate 17, at one end thereof, the said jaw being'hereinafter termed astationary jaw.

- A substantially U- haped clamping jaw 26 is provided withlongitudinally extending recesses 27, constituting uideways to 'receivethe track 20 formed y the projecting edges of the plate 19, thuspermitting the jaw '26 to slide relatively to the bed plate 17 and thestationary jaw 25, the mentioned jaw 26 constituting the movable jaw ofmy device. A horizontally extending shaft 28 has the ends thereofmounted in the sides 29 of the movable jaw 26 and rigidly mounted on theshaft are a plurality of locking dogs 30 having their under sidesprovided with teeth 31 adapted to operate over rack bars 32, rigidlymounted on the upper face of the plate 19. The ends of the shaft 28 arejournaled in elongated openings 33 in the sides 29 of the movable jaw26, thus permit a slight horizontal movement of the 34 being providedand terminating in a bifurcated cam head 35,

journaled on the shaft 28, between-the locking dogs 30, .a, suitablecollar 36 bei mounted on the shaft 28 between the bifurcated portions ofthe cam head 35.

In the use of my device, assuming that the movable jaw 26 is in spacedrelation to the stationary jaw 25, when a piece of work 37 has beenmoved between the jaws as shown in Fig. 3, the movable jaw 26 is slidforwardly to engage the piece of work, thus wedging the same between themovable jaw and the stationary jaw, the teeth 31 on the locking dogsbeing formed relatively to the rack bars 32 so that when the movable jawis slid forwardly the locking dogs will slide over the rack bars, thementioned locking dogs being adapted to lock with the rack bars toprevent the clamping jaw from being slid away from the stationary jaw,it being necessary to first move the locking dogs out of engagement withthe rack bars before the movable jaw can he slid rearwardlys When theclamping jaw has been moved forwardly to engage the piece of work 37, arearward pull is exerted on the cam lever 34, thus moving the cam headinto engagement with the rear face of the movable jaw and causing thehorizontal shaft to slide in the openings 33, thus advancing the movablejaw a sufficient distance toward the stationary jaw to rigidly clamp thepiece of work between the said jaws, the final position of the cam head35 being adapted to retain the movable jaw in locked position, while thelocking dogs 30 will also aid in retaining the movable jawv instationary position on the plate 19.

By providing the ball member l2,mounted as mentioned heretofore, whenthe cap 14 is partially unscrewed from the base 10, the upper part ofthe device can be swung to lie at an angle to the vertical plane of thebase,

after which the cap is rescrewed on the base 10 to secure the ball'member 12 in rigid position, thus enabling the operator to operate onthe work from any desired angle or position.v j

. Having thus described my invention, I claim:

1.. A device of the character described comprising a base, a memberdisposed above and in a longitudinal plane with the base and providedwith a fixed jaw, another jaw movable toward and away from said fixedjaw and provided with oppositely. disposed elongated openings, a shaftcarried by the latter mentioned jaw and having the terminals thereofextended through said elongated openings, and means mounted on saidshaft and having portions thereofengaging with said movable jaw and saidmember whereby the former is positively heldin locked position on thelatter,

2. A device of the character described including a bed plate having afixed jaw, a movable jaw, said movable jaw being provided with a rearwall and oppositely disposed side walls, the latter mentioned wallsbeing provided with elongated openings, a shaft carried by the movablejaw and having its terminals extended through the elongated openingsformed in the side walls thereof, and means fulcrumed on said shaftandhaving a portionthereof engaged with the inner face of the rear wallandanother portion thereof engaged with the base plate for locking the saidmovable jaw in relative adjusted positions on said bed plate. Intestimony-whereof I aflix my signature in presence of two witnesses.
